Description

Subtracting from 20 is an important 1st Grade math standard that includes learning subtraction strategies, finding differences with missing numbers in all positions, and relating addition to subtraction to name a few.

This resource was created to provide year-round practice for subtraction from 20, subtraction strategies, and word problem solving skills.

It consists of several types of worksheets and assessments that start at the end of Kindergarten level, and progressively go towards mastery of the 1st Grade Common Core Standards for subtraction from 20.

This resource will take you from day one to day 180! You’ll find plenty of practice for teaching and re-teaching, pre and post-assessments, all with answer-keys! Ideal for differentiating instruction.

This resource is organized in 3 files. The first one has sheets for subtraction practice. The second one has sheets for word problem solving practice, and the third one has assessments for each of the skills.

Standards

to see state-specific standards (only available in the US).
Understand the meaning of the equal sign, and determine if equations involving addition and subtraction are true or false. For example, which of the following equations are true and which are false? 6 = 6, 7 = 8 - 1, 5 + 2 = 2 + 5, 4 + 1 = 5 + 2.
Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 - 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
Relate counting to addition and subtraction (e.g., by counting on 2 to add 2).
Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem.
